Why is Mercury Labs falling/rising?

As of 13-Jun, Mercury Laboratories Ltd's stock price is currently at 879.00, reflecting an increase of 41.25, or 4.92%. The stock has been gaining for the last three days, with a total return of 7.33% during this period. It outperformed its sector by 5.21% today and reached an intraday high of Rs 889, indicating positive momentum. However, despite this recent uptick, the stock has shown a decline of 1.24% over the past month and a significant drop of 6.07% over the past year. The company faces challenges with weak long-term fundamentals, including a -0.76% CAGR growth in operating profits over the last five years and a substantial decline in profits of -44.5% over the past year, contributing to a perception of expensive valuation compared to peers.
In the broader market context, the stock's short-term performance is notably better than the Sensex, which has declined by 1.30% over the past week. While Mercury Laboratories has shown a positive return of 6.03% in the same timeframe, its year-to-date performance remains negative at -1.90%, contrasting with the Sensex's gain of 3.81%. This divergence highlights the stock's recent strength against a generally weak market backdrop, although the long-term outlook remains concerning due to its flat results and low cash reserves.
